FROST-PROOF STOP AN o WASTE VALVE.

SPECIFICATION forming part of Letters Patent No. 688,329, dated December10, 1901.

Application filed June 27, 1901.

To all whom it may concern.-

Be it known that I, WILLIAM H. OSBORN, a citizen of the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented a new and useful Frost-Proof Stop and WasteValve, of which the following is a specification.

My improvement relates to stop and waste valves which automatically shutoh the water and drain the house-pipes in order to prevent freezing; andthe objects of my improvement are, first, simplicity; second,durability; third, inexpensiveness of manufacture, and, fourth, to avoidthe use of springs in a device of the class named. I attain theseobjects by means of the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 is a plan view, and Fig. 2 a verticalsection.

Similar reference characters refer to similar parts throughout the twoviews.

The hollow casting 1, the weight 2, and the lever 3 constitute the bodyof the device.

1 is the hollow body portion of the device, which contains the workingparts.

2 is the weight at the end of an arm or lever.

3 is an L-shaped arm or lever which carries weight 2 on its outer endand is fulcrumed on a pin at its opposite end in the angle of the L.

4 is the threaded portion of the wall of the projecting opening, whichconnects with the house-pipe.

5 is the threaded projection for the waste.

6 is the threaded end of body portion 1 where the supply-pipe isattached by a union.

7 is the house-pipe opening in 1.

8 is the Waste-opening in 1.

9 is the supply-union.

10 is the operating-rod, upon fuller-balls are placed.

11 is the adjusting-nut.

12 is a metal collar which keeps a fullerball in place.

13 is the adjusting rubber fuller-ball.

14 is the stationary rubber fuller-ball. is its metal backing-flange.

16 is the piston, bored and threaded to receive 10 and slotted toreceive the L. portion of 3.

17 is the gland of the stufiing-box.

18 is the stuffing-box.

which the Serial No. 66,315. (No model.)

19 is the packing.

20 is the L extension of 3.

2.1 is the'pin upon which 3 is fulcrumed.

22 represents the two bracket members integral with body 1, which carrypin 21.

23 represents legs or attaching-brackets.

24 is a lug on 2.

25 is a hole through 24.

26 is the supply-chamber.

27 is the waste-chamber.

28 is the waste-port.

29 is the supply-port.

The body portion 1, together with legs 23 andbrackets 22, is in onepiece and cored out. The threads 4, 5, and 6 are cut on the outside ofthe openings. The end of body 1 for the piston is tapped out to receivethe stuffing-box 18, and the latter is tapped out to receive the gland17. The piston 16 is drilled and tapped in its inner end, and 10 isscrewed longitudinally into it. The piston 16 is operated by theprojection 20 of lever 3, and the valve is kept closed by gravity bymeans of weight 2. The weight 2 is provided with a log 24, which ispierced with a hole for attaching a chain or cord for operating thevalve.. The fuller-ball 13 is adjustable by means of the adjusting-nut11, so that the supply and rapidity of waste may be regulated accordingto the service-pressure.

My device operates in the following manner: The supply is connected at 6by means of the union 9. The opening 7 is connected with the house-pipeand the waste-pipe at 5. The waste is led to the sewer. Normally thesupply-port 29 is closed and the waste-port 28 i open, so that the waterin the house-pipe passes through waste-port 28 into waste-chamber 27 andthrough opening 8 to the sewer. To admit the supply, weight 2 is raisedby means of the chain or cord attached at 25, piston 16 is pushed in by20, fuller-ball 14 closes waste-port, and at the same time supply-port29 is opened. To cut off the water from the house, it is necessary onlyto release weight 2, which by its fall automatically and permanentlyshuts off the supply and opens the waste.

. I am aware that devices for thesame purpose have been inventedwithsprings and more complicated combinations. I am of course also awareof my application for patent on a somewhat; similar device, Serial No.725,508, dated December 1, 1900. Therefore I do not claim the devicebroadly; but,

Having thus described my invention, so that any one skilled in the artto which it pertains maymake it, what I do claim as myinvention, anddesire to secure by Letters Patent, is-

1. In a combined stop and waste valve, the combination of a hollowcylindrical body portion, a stuffing-box in one end of said bodyportion, a piston operating through said stuffing-box, an operating-rodscrewed axially into the inner end of said piston, a supply and a wasteport in the body portion, and a stationary and an adjustable fuller-ball on the operating-rod, so disposed as to close the portsalternately, substantially as specified.

2. In a combined stop and waste valve, the combination of a body portionformed of a single piece, a stufifing-box screwed into said bodyportion, a piston passing through said stuifing-box, an operating-rodscrewed into the inner end of said piston, a stationary fuller-ball onthe end of aforementioned rod adjacent to said piston, an adjustablefullerball on the end of the operating-rod opposite the piston, anadjustable nut on the said end of the operating-rod, the said piston,operating-rod, fuller-balls and adjusting-nut all disposed and operatingon the horizontal axis of the cylindrical body, and a fulcrunied andweighted lever to operate said parts, substantially as specified.

3. In a combined stop and waste valve, the following combination: acylindrical body portion 1; in said body portion 1 a servicepipe opening6, a house-pipe opening 7, awaste-opening8,asupply-chamber26,awastechamber 27, a supply-port andvalve-seat 29, and a waste-port and valve-seat 28; a stuffing-box 18screwed longitudinally into one end of the body portion; a piston 16slotted on its projecting end and passing through aforesaidstufling-box; an operating-rod threaded on both ends, and one endscrewed longitudinally into the inner end of piston 16; a stationaryfuller-ball 14 and a metal flange 15 disposed on the end of rod 10adjacent to piston 16, an adjustable fuller-ball 13, flange 12 andadjusting-nut disposed on the end of rod 10 opposite the piston; a lever3 fulcrulned at 21, an L projection on lever 3 passing upward throughthe slot in piston 16; and a bracket 22 integral with body 1, allsubstantially as and for the purpose specified.
